Miss Lipin was genuinely taken aback, extremely shocked.
"Guesswork." Su Rong looked at her and speculated, "Moreover, this evidence should also be known by the Fourth Prince, otherwise, he wouldn't have pleaded with the Eastern Palace, and wouldn't have assured your innocence so resolutely, to the point of risking his life for your innocence."
Miss Lipin slowly nodded, admitting that her theory was right, and said in a lowered voice, "In Feng Si's house, the large black cabinet in his room, under the third brick, something my father left for me is hidden. I don't know what evidence it is, but my father said, that if he were to die one day and my life were also in danger, I should take it out. I don't trust anyone enough to dare to do it, what you said is right, I don't trust the Rui'an King, he is too smooth, too good at judging the situation. He might not be able to help a Fourth Prince without any foundation like me."
